mam wrong notes is given pls check and update it pls

[@harleenkaur6188]

atomic no is more appropriate because when we know the atomic no we know the protons and protons is equal to electrons and when we know about the electron we find the shell of element and physical and chemical properties of the element and make the elements arrange on the basis of same physical and chemical properties X element is aluminium amazing session as ALWAYS BY OUR OWN AG MAM

[@Rakeshkumar-fi1cn]

Very Good.

[@viddhartharya6430]

Hi

[@suruchisinghrathore]

Study starts from 6:26 👍👍👍

[@pradeepsinghfromsgs7481]

Waste kaha homework discussion hai question ka

[@Vinayak-m9w]

No tanks

[@virmani4013]

Yes it’s true that the atomic no. if an element is considered to be a more appropriate parameter than its atomic mass for a chemist because they just come one after the other as a whole no. instead of any decimals in between whereas atomic masses can be hoti many decimals so we cannot find how many elements are there in between. Example: element X(atomic no. 13) Electronic configuration 2,8,3 It belongs to period 3 and group no 13 Really enjoyed the session 👍👍 Session was amazing👏👍

[@arjunsharma8321]

Can't understand poor explanation

[@vijayajayananda1012]

Perfect ans thank you 🙏

[@taniskasaxena2538]

I pray to God that we all may get above 95 percent in boards💯✌️

[@kanakgoel2969]

Homework question Ans. Atomic no. Acts as an uniquely identification key for all the elements where in atomic masses we cannot say that in future there might not be any discovery of element that have atomic mass in between two which may change the order of the elements.Also There are many isotopes and isobars which have either a common no. or mass Or different mass or no.due to which there cannot be a fix position in atomic mass based periodic table

[@zebawase6494]

We have arranged our periodic table using atomic no as it helps to overcome with the problem of isotopes which had to be clubbed within the same column . This created problem in the older periodic table .

[@Rkg45398]

The session pdf is for the series of vip series of acids bases and salt . Mam pls go through the link.

[@mehjabeenbano7477]

Yes mam i can do it also I will do it...... 😊😊😊 amazing session mam🥰🥰🥰😍😍😘😘😘thank u so much.....

[@unknown-ur1gv]

Wow one more स्प्रिंट X thank you ma'am very much 😊😊😊😊😊😊🙏🙏🙏🙏🙏🙏👍👍👍👍👍👍😁😁😁😁😁😁

[@roshni3446]

Atomic no. = 13 Electronic configuration of element 13= 2,8,3 From the configuration we identify that The element Is from 13th group And by no. Of shells is from 3 rd period.

[@Kk_179]

Hw ans because by atomic no. We can find its configuration and can find it chemical property. Eg - Al whose valency is 3 so we can find its chemical properties.

[@inspirationaltalkswithsanj8514]

Homework answer--- 1) calcium 2) b

[@brettcooper2326]

That was actually pretty good ma'am - 7:15

[@dikshadiksha4250]

Q1 B calcium

[@Aartisharma-pk6xr]

H. W X: it is placed in 3 period and 13 group and it is metal and less electropositive and less atomic raddi. Loved this sessiom ❤❤

[@srajalsahu9348]

Hw..... Atomic no. Of any element is natural no. & atomic mass can be point so atomic no. Is more appropriate to understand and classify by chemist.... & awesome session by uhh mamm....

[@MRSVDGAMER.]

Homework answer is X Element is Aluminium whose atomic no. is 13 ...... Amazing session as always ma'am From Drimy Jain 🌹🌹

[@ANANYA_KOVER.]

Answer of 1 - calcium Answer of 2- C

[@Kk_179]

Q8 A) 3rd period 17 group 4th period 2nd group

[@dharmendrabhardwaj323]

Q3 B

[@soupat481]

ISOTOPES AND ISOBAR DIFFER AS THEY ARE IN ATOMIC MASS AND IF MORE ELEMENT AE DISCOVERD THAN THEY CAN CREATE PROBLEMS AS IF WE HAVE ATOMIC NO 13 THAN WE CAN EASILY FIND ITS GROUP AND PERIOD

[@igadityayt7104]

If I can dream it and I can do it🤗😊

[@Kk_179]

Q8 B) non-metal , metal

[@MehakthC]

Element is aluminium because it's atomic no. Is 13 and e.c 2,8,3 Session is amazing mam❤️❤️🎉🎉🎉

[@architadas_13]

8. Cl- non metal acidic oxide Ca metal basic oxide CaCl2

[@haarikaalla1665]

Mam u teach so good

[@VedantuClass9_10_11]

Thanks a lot!

[@rameshkumarsingh480]

Thank u so much ma'am ji😘😊

[@dikshadiksha4250]

Q2 (B)

[@architadas_13]

5. It was done so that the elements with same properties should be kept together

[@aditeekulkarni5662]

I can do it.. a year later for my boards of 2022, with silver ma'am.

[@uditgupta7903]

Hi mam Waiting for this awesome session 🙏 East ho ya west vdnt is best I Can , I Will Watch Me 🙏

[@ydtush05]

thankyou so much ma'am

[@shambhavigupta8150]

Homework Answer :- Through atomic no. we can able to know following things :- 1. No. of proton . 2. No. of electron (in stable atom). 3. Electronic Configuration. 4. Valency 5. Its physical and chemical properties.

[@rammusande4484]

Mam what's difference between atomic radius and mass??

[@prajwallakra]

hw answer the atomic no gives the no of proton in the element which is the fundamental property so its al - alluminium

[@mohinigharjale8208]

Yes mam we will do it.....just see 🙏🙏🙏🙏

[@ishikaarora928]

Hw ans. Because by atomic no we can conclude the valency of an atom like 13 is the atomic no of alluminium. So it's valency is also 13

[@khushikalamkar7673]

Homework 1) the atomic no gives the no of protons which gives the fundamental property and no of electrons

[@maandrpm]

Yes ma'am I can do it 😊

[@prakashchandragupta334]

Amazing session ma'am!😊💯 And I have reached at 'I can do it' step and I'm sure that in sometime I'll reach my destination i.e., 'Yes, I did it!' Thank you for such a motivational quote as well as for everything.☺☺

[@Kk_179]

Q8 C) cao, basic

[@neerajkhillan9792]

Carbon is having maximum valency Amazing session 🌻🌻

[@anishamajumder1940]

h.w. :- Atomic no. of X is 13 . therefore electronic configuration is 2,8,3 . therefore group no. is 13 and period no . is 3 . thus, position of element in modern periodic table is justified . but if we consider atomic mass then it would be a bit inappropriate .

[@anusreekarottel6029]

QUESTION 1)B (CALCIUM)

[@anusreekarottel6029]

QUESTION 2) B (i, ii and iii0

[@AnshuKumar-fh9du]

Q no. 1 calcium

[@ayushi10pathak7]

Amazing session mam

[@anusreekarottel6029]

HW ANS:- ATOMIC NO GIVES US THE NO OF PROTONS WHEREAS ATOMIC MASS GIVES US THE SUM OF NO OF NEUTRONS AND PROTONS IN THE NUCLEUS OF AN ATOM. WHEN ATOMIC NO INCREASES BY ONE FROM ONE ELEMENT TO THE OTHER DO NOT VARY REGULARLY FROM ONE ELEMENT TO ANOTHER. THAT IS WHY ATOMIC NO IS AN APPROPRIATE PARAMETER THAN ATOMIC MASS. EXAMPLE--> ELEMENT X(atomic no 13) WHICH IS ALUMINIUM. ITS ELECTRONIC CONFIGURATION IS 2,8.3
